/**
 Provides a small and fast bytecode manipulation framework.

 <p>
 The <a href="http://www.objectweb.org/asm">ASM</a> framework is organized
 around the {@link net.hasor.core.classcode.asm.ClassVisitor ClassVisitor},
 {@link net.hasor.core.classcode.asm.FieldVisitor FieldVisitor},
 {@link net.hasor.core.classcode.asm.MethodVisitor MethodVisitor} and
 {@link net.hasor.core.classcode.asm.AnnotationVisitor AnnotationVisitor} abstract classes,
 which allow one to visit the fields, methods and annotations of a class,
 including the bytecode instructions of each method.

 <p>
 In addition to these main abstract classes, ASM provides a {@link
net.hasor.core.classcode.asm.ClassReader ClassReader} class, that can parse an
 existing class and make a given visitor visit it. ASM also provides
 a {@link net.hasor.core.classcode.asm.ClassWriter ClassWriter} class, which is
 a visitor that generates Java class files.

 <p>
 In order to generate a class from scratch, only the {@link
net.hasor.core.classcode.asm.ClassWriter ClassWriter} class is necessary. Indeed,
 in order to generate a class, one must just call its visit<i>Xxx</i>
 methods with the appropriate arguments to generate the desired fields
 and methods. See the "helloworld" example in the ASM distribution for
 more details about class generation.

 <p>
 In order to modify existing classes, one must use a {@link
net.hasor.core.classcode.asm.ClassReader ClassReader} class to analyze
 the original class, a class modifier, and a {@link net.hasor.core.classcode.asm.ClassWriter
ClassWriter} to construct the modified class. The class modifier
 is just a {@link net.hasor.core.classcode.asm.ClassVisitor ClassVisitor}
 that delegates most of the work to another {@link net.hasor.core.classcode.asm.ClassVisitor
ClassVisitor}, but that sometimes changes some parameter values,
 or call additional methods, in order to implement the desired
 modification process. In order to make it easier to implement such
 class modifiers, the {@link net.hasor.core.classcode.asm.ClassVisitor
ClassVisitor} and {@link net.hasor.core.classcode.asm.MethodVisitor MethodVisitor}
 classes delegate by default all the method calls they receive to an
 optional visitor. See the "adapt" example in the ASM
 distribution for more details about class modification.

 <p>
 The size of the core ASM library, <tt>asm.jar</tt>, is only 45KB, which is much
 smaller than the size of the
 <a href="http://jakarta.apache.org/bcel">BCEL</a> library (504KB), and than the
 size of the
 <a href="http://serp.sourceforge.net">SERP</a> library (150KB). ASM is also
 much faster than these tools. Indeed the overhead of a load time class
 transformation process is of the order of 60% with ASM, 700% or more with BCEL,
 and 1100% or more with SERP (see the <tt>test/perf</tt> directory in the ASM
 distribution)!
